RUDOLPH FAAS, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONEIIALF TO MARX\VINEMAN, OF SAME PLACE.

CAR-AXLE LU BRICATO R.

SPECIFICATION forming part of Letters Patent No. 338,051, dated March16, 1886.

Application filed December 10, 1885. Serial No. 185,216.

To all whom, it may concern:

Be it known that I, RUDOLPH Finis, a citizen of the United States ofAmerica, residing at Chicago, in the county of Cook and State ofIllinois, haveinvented certain new and useful Improvements in LubricatorDevices for Car-Axle Journals, of which the following, in connectionwith the accompanying drawings, is a specification.

The purpose of my invention is to provide improved means for the purposeof lubricating the journals of car-axles.

Heretofore it has been common to lubricate thejournals by placingcotton-waste, soaked in oil, under the journal in the cavity of the box.By using cotton-waste for this purpose there is a liability of ignitionor combustion of the waste, owing to its oily condition and the frictionproduced by the rotation of the journal against its bearing. Rollershave also been yieldingly supported in the car-axle box, so as to bearagainst and lubricate the journal. My invention consists, chiefly, incertain novel means which I employ for supporting the lubricating-rolleryieldingly in such a manner that it will feed or supply oil to thejournal for lubrication.

Another important feature of my invention consists in making thefeed-roller of cork or other equivalent porous material. There are alsocertain minor features or details of' construction appertaining to myinvention. and which I will hereinafter fully describe.

In the drawings, Figure 1 is a vertical crosssection of a car-axle box,showing the relation of my improvements thereto and to the journal, andalso showing the relation of the box to its supporting-frame. Fig. 2 isa top view 40 of a device embodying my improvements, en-

larged and detached or removed from the box. Fig. 3 is an end view of mylubricating-roller, and also showing my mode of mounting it yieldingly,and so that it may be arranged in and removed from the box withfacility; and

Fig. 4 is a detail, the same being upon an enlarged scale, and showingthe means employed for the purpose of providing the roller withadjustable bearings.

Like letters of referenceindicate like parts.

(No model.)

A represents the car-axle box.

13 is one of thejournals of the car-axle.

C is one of the brasses or journal-bearings.

As my invention does not relate to the construction of the car-axle box,or to the means employed for providing suitable bearings for the axle, Ihave not shown the same with particularity, and I desire to state thatmyimprovements maybe applied to the use for which they are intended, inconnection with any well- 0 known construction of car-axle boxes.

D is a frame or bent or angular plate, made, by preference, of malleableiron; but it may be made of any suitable material.

. E E are curved springs arranged parallelly and depending from theupper corners of the frame I).

F is a crossbar connecting the springs E E, for the purpose ofpreventing too much lateral movement.

G G are curved springs attached to the lower part of the frame D andextending upward. The springs E E, as will be clearly perceived onreference to Fig. 3, rest or bear upon the upper ends of the springs GG.

H H are bearing-blocks attached to the lower ends of the springs E E.

I is a roller, made of cork; but it may be made of equivalent absorbentmaterial.

J J are plates set into the ends of the roller I, and there secured bymeans of screws a a or other suitable fastenings. The inner faces ofthese plates have thereon the projections or central extensions, b b.

K is a rod passing centrally through the roller I and havingscrew-threaded ends entering the projecting parts I) I), thus securingthe end plates firmly in their proper places.

In the outer faces of the plates (4 a are central depressions orindentures, c c.

L L are pointed screws passing through the bearings H Hand turning infemale screws therein. The points (I d enter the depressions orindentures c c, which are sufficiently flaring not to bind upon thepoints of the said screws.

M M are jam-nuts run upon the screws L L between their heads and thebearings H H, for the purpose of preventing the accidental turning ofthe screws after the latter have been set or adjusted. The heads ofthese screws are adapted to be turned either with a screw-driver orother suitable tool.

It will be perceived, from the foregoing description, and from referenceto the drawings, that the frame or plate D, in connection with thesprings E and G and the roller I, may be set into the box A in such amanner that the roller I will be in contact with the journal B.

If it be understood that oil be poured into the box to the heightillustratedf0r example, at e, Fig..1-for the purpose of lubricating theaxle, it will be perceived that the rollerI will also be to a greater orless extent submerged in the oil. The roller I by being mounted on thesprings F and G in the manner described will yield toall the usualmovements of the journal while being rotated by the latter. It will alsobe perceived that as the roller I is supported by and turns on thepointed ends of the screws L L the rotation of the roller I will beopposed by a very slight degree of friction, and the screws L L, bybeing adjustable, may be set in or out more or less, so as tocompensatefor wear, and'so as to hold the roller I sufficiently awayfrom the bearings H H and the springs to which they are applied.

By employing the jam-nuts M M, Iam enabled to prevent accidentalrotation of the screws L L.

I desire to state that two of these devices embodying'my invention maybe arranged in the same box, if'desirable or necessary. The bar F aidsin preventing" the roller I from being swayed laterally or in thedirection of its ends. It will furthermore be perceived that as thejournal B rotates while in contact with the roller I, and while thelatter is in the lubricating-oil, the oil will be fed or carriedcontinually to the journal, thus keeping it lubricated.

By making the roller I of cork it is light and flexible, and at the sametime durable, as well as to some extent porous.

By making the roller of cork or other suitable porous material the oilabsorbed by the same will continue to lubricate the axle after together,substantially as and for the purposes the oil in the box has in otherrespects been exh ansted. The centrifugal foree ef-the rotating rollerwill cause the oil absorbed thereby to move out toward its perimeter,and thus keep the axle in an oily condition. The roller will alsoperform its functions in a neat and clean manner.

It is obvious that the principle of my invention may be reduced topractice without employing all the details of construction which I havenow described with particularity, and while I deem the features which Ihave'shown and described to be the best for the purposes set forth, I donot here intend to restrict myself to such details or minor features ofconstruction. I desire to state, however, that it is not new with me toemploy avertically-yieldipg roller for the purposes set forth andIdo-not, 5 therefore, here intend-to claim tlhesame, broadly; but,

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, in alubricatingdevice for car-axle journals, of theframe or plate I), the springs E E, the spri ngsG..G,=and the-roller I,mounted in bearingson thesprings E'E, substantially as and forthepurposes specified.

2. The'combi-nation .o-fthe-frame or plate D, the springs E E, having ontheir eudsthe bearing-blocks H H, the roller '1, and theadjnstabletapering centering-screws L L, substantially as and for thepurposesspecified.

3. The combination-of the frame'or plate 1). the springs E E, springs .GG,'.the rolier' ;I, the bearings H H, the screws L L, the nuts M M, andthe plates J J, all-constructed and arranged specified.

In testimony that Iclaim the foregoing as my own 1 hereunto afiixm-ysignature in presence of two witnesses.
